Q. Consider the following statements regarding the electromagnetic spectrum:

1. Gamma rays have higher frequency than X-rays.
2. Microwaves have a higher energy than radio waves.
3. Infrared has longer wavelengths than ultraviolet.

Which of the above statements is/are correct?
Answer: 1, 2 & 3
Notes: All statements are correct: Gamma rays possess higher frequencies than X-rays; microwaves have higher energy than radio waves, as they have greater frequency; and infrared radiation has longer wavelengths than ultraviolet. This reflects the order of electromagnetic spectrum characteristics in terms of frequency, energy, and wavelength.
